KOLMEN OSWALD, OF NEW YORK, N. Y., ASSIGNOR TO C. MAURICE PEABODY, OF SOUTH ORANGE, NEW JERSEY.

WATCI'IMAN S CLOCK.

Application filed February 28, 1916.

To all 'whom it may concern:

Be it known that I, KOLMEN OswALD, a subject of the King of Hungary, and a resident of the borough of Manhattan7 city, county, and State of New York, have invented certain new and useful Improvements in Watchmens Clocks, of which the following is a specification.

This invention relates to key-actuated marking mechanism such as is employed in watchmens clocks, and the objects of the invention are to improve key-actuating marking mechanisms more particularly in relation to watchmens clocks.

To the accomplishing of the above objects and to such others as may hereinafter appear, the invention comprises in a watchmans clock a series of impression members normally locked against movement, a key barrel arranged to hold a key which is adapted to unlock and actuate said impression members; the locking means for said impression members being arranged to operate as soon as the key is withdrawn.

While the invention is to ybe described with particular reference to the details of construction, it is not to be considered as limited thereto, as many changes can be made and still fall within the scope of the invention set forth in the appended claims.

Referring to the drawings:

Figure lvshows a face view of a clock provided with my improvedmarking mechanism, the cover of the clock being shown in open position to show the dial.

Fig. 2 shows a bottom end view of the clock.

Fig. 3 isa view of the underside of the stamp plate. Fig. 4 shows a fragmentary view of the removable plate, the stamp plate having been removed.

Fig. 5 is a longitudinal sectional View of the key actuated marking mechanism.

Fig. 6 is a bottom view of the key actuated marking mechanism.

Fig. 7 is a view similar to Fig. 5, showing the key operating the impression members.

suitable clock work, not shown, and 4 designates an impressible dial of paper or some like material mounted on said arbor to rotate therewith. The dial Vcommonly has printed upon it suitable lines and numbers denoting hour spaces. Adjacent the movement plate 6 is a removable plate 7 which supports a stationary printer or stamp plate @i the underside of the upper end of which is cut away to permit of the edge of the dial 4 passing underneath the same. Directly underneath the stamp plate 8 is situated, in the plate 7, a longitudinal slot 9, through which slot the marking arms of one or more impression members 10 may project to force the dial 4'against the underside of the stamp plate 8 and so mark the dial. The marking plate 8 has on its underside suitable matrices as shown in Fig. 3, which correspond to the numerals on the arms of Vthe impression members 10 as shown in Fig. 4.

|Ihe impression members 10 are in the ypresent instance six in number, although more or less can be used as desired depending upon circumstances. The impression members 10 are arranged side by side and are pivoted at one end upon a rod 11 the ends of which are secured to the depending side plates 12 and 18 secured to the underside of the plate 7 through the medium of the cross plates 14 by means of screws 15.

Adjacent the free ends of the impression members 10 is located a key barrel 16 rotatably mounted at each end in the depending plates 12 and 13. In the present instance the key barrel is provided with two longitudinal slots 17 and 1S adapted to be entered by the corresponding wardsY 19, 20 and 21 of the key 22.

The key barrel 16 is normally held in locked position by means of a locking pin 23 the free end of which engages the slot 17. r1`he locking pin 23 is slidably mounted together with a spring 24 in a block 25 secured to the side plate 12.

The impression members 10 are normally held in locked position by means of a locking plateV 26 provided with a locking lip 27 which engages the locking shoulders 2S adjacent the pivoted end of every impression member. The locking plate 26 is in the present instance secured to a cam plate 29 which supports the same through the medium of a pivot pin 30 secured to the side plate 13. The locking plate 26 is provided with an arm 31 the outer end of which is connected to a cross rod 32 secured to the vside plates 12 and 13 by means of a spring 33.

rlhe spring 33 acts to force the locking lip 27 of the locking plate 26 upward into engagement with the shoulders 28 of the im pression members 1() which are all forced downward through the medium of a flat spring 34 as shown in Fig. 5. Y

Each impression member 10 is provided with an upwardly projecting arm 35 and the top of each arm is provided with a numeral so as to mark they dial 4 when one or more of the projecting arms are forced into contact therewith.

When it is desired to mark the dial 4 at any given time a suitable key 22 is inserted in the key barrel 16, the inclined end 36 of the ward 19 operating to push the end of the locking pin 23 out of the slot 17 so as to release the key barrel as shown in Fig. 5.` The key and key barrel are then turned in a clockwise direction so that the Ward 21 of the key will engage the cam face 37 of the cam plate 29 to force the locking lip 27 out of engagement with the shoulders 28 thereby releasing all of the impression members 10. The ward 2() of the key is then free to force one of the impression members l0 upward so that the numeral on its upwardly projecting arm will make an impression on the dial 4 by being forced thereagainst, as shown in Fig. 7. When the key is then turned in a counter-clockwise direction the ward 21 on the key acting against the cam face 37 holds the locking lip 27 against the action of the spring 33 until the impression member 10 previously operated is returned to its normal position with the other impression members 10 by the action of the spring 34, so that when the ward 21 on the key is out of engagement with the cam face 37 the locking lip 27 will again engage the shoulders 28 of all the impression members, thereby locking the same.

By providing different keys with different wards corresponding to the ward 20 any individual impression member or group of impression members can be operated to mark the dial.

The key barrel 16 is preferably limited in its movement beyond its eXtreme working position in either direction by means of a safety block 38 suitably secured to the outside of the key barrel by means of suitable screws 39.

The left hand side of the safety block 38 is provided with an extending side portion 40 which is adapted to engage suitable shoulders 41 formed on the free ends of each of the impression members 10, which limits the movement of .the keybarrel in a counterat 43 so as not to engage the cam face 37 when in the position shown in Fig. 5.

The key barrel 16 is preferably provided with a central partition 44 adapted to fit the slot 45 in the key. The key barrel. is also provided with a series of inwardly projecting screw ends or guards 39 and 46 which fit corresponding grooves 47 in the key. By providingdifferent key barrels in different. clocks with varying length of partitions 44 and varying positions of guards 46 different keys will be required in each case.

It is practically impossible to pick and operate the impression members by means of ay skeleton key or similar instrument other than a key made especially for the purpose, for the reason that the impression members. are locked and the springs 33 and 34 are always operating to keep the same in locked position and if an instrument can be used to release the locking plate 26 it will fly into locked position before the impression members can be operated.

To eachclock there is provided a plurality of keys similar to the key 22, the number of keys depending upon the number of places the watchman .is required to cover in his rounds, each place being provided with a key usually secured to the wall in a suitable box. These keys are usually all made alike with the exception of being provided with different se ries of wards 20 so that each key will operatc a different series of impression members 10 so that the impression made by each key on the dial 4 will designate not only the time but the place of recording.
